7. Tiger shark vs. Turtles

A contest between one of the most aggressive sharks in the ocean and a gentle turtle would seem a foregone conclusion. However, despite all its strength and power, the Tiger shark still has to get its teeth through a rock-hard carapace. The shark has the key advantage of not needing to come up for air. This makes loggerheads, who come up for air for two minutes at a time, extremely vulnerable to an attack from below. Green turtles, however, take a gulp of air for about one second, before returning to the safety of the sea bed, and largely avoid the perils of a shark attack.
